The high level of atmospheric pollution is a global problem that has taken on particular significance in recent years and will continue to grow in the near future. Air pollution directly affects the health, living organisms, vegetation, water, soil and buildings. Additionally, it moves easily even over long distances. Certain air pollutants influence the climate, cause negative processes in the pr...

The Ozone Secretariat has prepared three briefing notes to support parts A, B and C of the 9 – 10 July 2018 Vienna workshop on energy efficiency opportunities in the context of phasing-down hydrofluorocarbons (HFCs). This briefing note, intended for part C, discusses the promotion of efficient refrigeration, air-conditioning and heat pump (RACHP) equipment, looking in particular at: the most commo...

This report models the climate change mitigation potential of fossil fuel subsidy reform across 32 countries. The results show how much greenhouse gas emissions—both in per cent as well as in absolute terms—countries can save by 2030. In addition, the model also calculates the subsidy savings countries can gain from fossil fuel subsidy reform. Countries can further increase their emission reductio...

A new World Bank report examines how subsidy reform can help safeguard the world’s foundational natural assets—clean air, land, and oceans. These assets are critical for human health and nutrition and underpin much of the global economy. But subsidies for fossil fuels, agriculture, and fisheries are driving the degradation of these assets and harming people, the planet, and economies. This money -...

Countries around the world agreed to reduce fossil fuel subsidies. It is one of the Sustainable Development Goals (SDGs) that they want to reach by 2030. The maps here show two indicators to track this goal. They are part of our SDG-Tracker where you find all of the available measures to track the SDGs. In many countries fossil fuel subsidies are extremely high. The New York Times reports that in ...

The ARP was the first national cap and trade program in the country and it introduced a system of allowance trading that uses market-based incentives to reduce pollution. Reducing emissions using a market-based system provides regulated sources with the flexibility to select the most cost-effective approach to reduce emissions, and has proven to be a highly effective way to achieve emission reduct...

In 2014, Chile passed a large tax reform which notably included the introduction of three new environmental taxes: A carbon tax, a tax for local pollutants and a tax for new vehicles. Chile’s environmental framework has been widely strengthened through the introduction of the new green tax regime, procuring additional, cost-effective instruments for the environmental authorities to fulfil their ob...

The EU ETS is a cornerstone of the EU's policy to combat climate change and its key tool for reducing greenhouse gas emissions cost-effectively. It is the world's first major carbon market and remains the biggest one....
